The most important part of everyday root canal treatment is diagnosis about the morphology of tooth, root and root canal. Usually this procedure is performed by visual examination and radiographic (panoramic/periapical) examination. However, 2-dimentional radiography has several limitations such as imposition of anatomic structures including buccal/lingual root canals and distortion of images. Recently, owing to the increased interest in dental implant and affordable cost of CBCT equipment, CBCT has been introduced widely in local dental clinics. CBCT is characterized by their lower radiation dose and shorter exposure time than conventional CT scan, and ability of 3-dimentional reconstruction of the dento-alveolar structure. Also in endodontic field, the data from CBCT could be very helpful in diagnosing complex root canal anatomy, apical periodontitis, cause of failure and in determining treatment plan. However, there are some limitations such as radiation dose and artifact. Therefore, clinicians should know about indication, advantages and limitations of CBCT, and properly use it for successful root canal treatment to save the natural teeth.

BACKGROUND/OBJECTIVES: Few studies have provided evidence of the association between diet quality and dental caries. This study aimed to examine the association between diet quality and untreated dental caries in a Korean representative population. SUBJECTS/METHODS: The study population included a sample of 13,815 participants, aged ≥ 19 from the Korea National Health and Nutrition Examination Survey during 2013-2015. The explanatory variable was diet quality and the outcome variable was untreated dental caries. Untreated dental caries were defined by the number of decayed teeth recorded according to the criteria established by the World Health Organization. Diet quality was defined by using the Korean Healthy Eating Index (KHEI) through the 24-h recall methods. We assessed the association between diet quality and untreated dental caries while adjusting for age, sex, education, income, smoking status, dental visits, toothbrushing frequencies, obesity, and diabetes mellitus. RESULTS: The mean overall KHEI scores in the untreated dental caries group were significantly lower than those in the group without untreated dental caries. Significant differences were observed in the untreated dental caries group based on the KHEI quartiles (P < 0.001). After adjusting for potential confounders, the quartiles of KHEI scores showed an association with untreated dental caries, demonstrating a dose-effect trend (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.35-1.84 for 1st quartile; OR, 1.38; 95% CI, 1.19-1.59 for 2nd quartile; OR, 1.32; 95% CI, 1.14-1.53 for 3rd quartile; reference quartile highest]). CONCLUSIONS: The findings indicated an inverse association between diet quality and untreated dental caries in Korean adults. Healthcare providers should take into account the significant role of diet quality in preventing and managing oral health.

Objectives: This study aims to contribute to the prevention of dental diseases and health care in the elderly by investigating the relationship among the experiences of chronic diseases, dental health status, and the behaviors in the Korean elderly people. Methods: A total of 2,856 elderly people aged 65 or older were selected as the final analysis subjects using data from the 6th National Health and Nutrition Examination Survey (2013-2014). Chronic diseases were defined as 'cardiocerebrovascular diseases', 'diabetes', 'chronic respiratory diseases', and 'cancer' diagnosed by the doctors. For the statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the relationship among the experiences of chronic diseases, general characteristics, dental health status, and the behaviors in the Korean elderly. Finally, logistic regression analysis was performed to investigate the relationship among the experiences of chronic diseases, dental health status, and the behaviors. Results:The prevalence of Cardiocerebrovascular diseases was significantly higher in the 3-4 group of community periodontal index with the score of 1.36 (95% CI 1.03-1.00) than in the 0-2 group. The prevalence of Cardiocerebrovascular diseases was significantly higher in the group without dental examination during the past one year with the score of 1.29 (95% CI 1.00-1.66). The prevalence of diabetes was significantly higher in the uncomfortable speaking state group with the score 1.46 (95% CI 1.12-1.91). The prevalence of cancer was significantly higher in the partial denture needs group with the score 1.67 (95% CI 0.98-2.83). Conclusions: Regular dental examinations and dental health care for the elderly with chronic diseases showed that periodontal health and residual teeth could be maintained and managed.

Prior to the start of the general oral examination, this study was performed using the theory of planned behavior to provide data that would help not only increase intention of industrial workers' dental care utilization after their dental examination, but develop the follow-up oral health programs. As the first research group, 608 workers were selected from the 1016 workers while excluding both 53 workers who were currently undergoing dental treatment and 355 workers who had an opportunity to visit the dental clinic over the previous six months. Among the general characteristics that would influence the 608 workers' intention to utilize the dental clinic within one (1) month, their financial state showed that the higher their financial abundance level, the stronger their intention to visit the dental clinic(p<0.01). It was shown that the attitude toward the dental care utilization related behavior and subjective norm except the perceived behavioral control among the TPB variables had a significant effect on their intention(p<0.01). Among TPB variables, attitude toward the dental care utilization and subjective norm except the perceived behavioral control, were significant correlation with behavioral intention(p<0.01). The structure model's R-square of the attitude toward the behavior, subjective norm and perceived behavioral control having and effect on the intention accounted for 21%. In order to encourage the workers to have positive thoughts about the attitude toward their dental care utilization and subjective norm, therefore, it is required to perform the continued oral health programs, in addi1ion to oral health experts' regular education.
